Q: Car runs with fuel line pulled and misses when it's attached

asked by on May 04, 2017

Carb has been rebuilt new plugs installed firing order is correct getting spark and fuel car starts and sounds terrible like it's missing and then dies. Pull the fuel line and plug it off start the car again it runs great until the fuel in the bowls is gone and then it dies. Installed a fuel pressure regulator and tried every psi from 1/2lb to 6.5 same results. What could cause this? Thank you in advance.
